PICKER STICK CHECK Filed April 24, 1947 2 Sheets-Sheet 2 Charles Gal/and B @mwia WW 3 M518 Patented Feb. 28, 1950 UNITED STAT ES PATENT; OFFICE 2,499,023 1 f PICKER- STICK CHECK Charles Galland, Fall River, Mass.

Application April 24, 1947, SeiialNo. 743,500 I This invention relates to a guard for the check strap of a picker stick of a loom and has for its primary object to efiect economies in weaving.

Another object is to reduce to a minimum the breakage of check straps in service, and not only efiect economies in material, but also avoid loom stoppage and consequent loss of production.

A further object is to facilitate the adjustment of the check straps on a loom and consequently effect saving of the loom fixers time.

The above and other objects may be attained by employing this invention which embodies among its features a strip of flexible material, a guard plate detachably secured intermediate its ends to each end of the strip of flexible material, each guard plate having an elongated slot opening thereinto through one end and a curved guard at the end of each guard plate remote from the slotted end to prevent the strip of flexible material forming the check strap from bending abruptly.

In the drawings,

Figure 1 is a fragmentary side view of a lay and picker stick showing this improved check strap and guard in place thereon,

Figure 2 is a top plan view of the lay, picker stick and check strap,

Figure 3 is a perspective view of a check strap and the guard plates, and

Figure 4 is a horizontal sectional View through the check strap and guard plates, showing the same attached to a conventional check strap holder.

Referring to the drawings in detail, a loom lay designated I is provided with a conventional elongated slot I l in which a conventional picker stick l2 moves in the ordinary manner. Carried by the lay I0 is a conventional guard and check strap holder or bracket l3 which depends from the lay and is provided in its depending portion with a bolt receiving opening l4.

My improved check strap and check stra guards designated generally [5 comprises a strip l6 of flexible material t each end of which is detachably connected as by a bolt l1, a guard plate designated generally l8. Each guard plate comprises a strip of metal [9 opening into one end of which is an elongated slot 20 for the reception of an attaching bolt 2| which passes through the opening M of the strap holder [3 and through the slots 20, with the plates lying in overlapped relation as illustrated in Figure 4. Each plate is provided intermediate its ends with an opening through which an attaching bolt IT projects,

and formed at the end of each plate remote from its slotted end-is a curved guard member 22.

The check strap is coupled to the loom by means of the check strap holder 13 through the opening I 4 in which the bolt 2| is thrust. The ends of the guards l9 having the slots 20 therein are arranged in overlapped position as illustrated in Figure 4 and the bolt 2| is thrust through the slots 20, adjustably to support the guards on the check strap holder I3. The flexible strip I6 is then attached to the guards [8 by the attaching bolts 11 and it is then adjusted to regulate the throw of the picker stick [2 by loosening the nut on the bolt 2| and sliding the guards It to the desired position and again tightening the nut. Obviously, as the picker stick approaches the end of its travel in either direction the check strap will be thrown alternately into the dotted line positions illustrated in Figure 2 so that the curved guard portions 22 of the guards I8 will so guide the flexible strip l6 as to avoid creating an abrupt bend therein which would be likely to cause its breakage. By thus guarding the abruptness of the bend in the flexible strip, its useful life will be materially extended and consequently the re placement of the flexible strip need not take place When it is necessary to replace the flexible strip, the nuts on the bolts I! are removed and the strip may then be disconnected from the guards I8 so that by cutting another strip of the same length and provided with openings the same distance apart, the strip may be replaced without, in any way, altering the adjustment of the guard plates 18. In this way, much time is saved in replacing worn or broken check straps with a resulting saving of the loom fixers time. ,Not only will time be saved, but also materials as the strip of flexible material employed is of considerably less length than that "required for check straps of the ordinary type.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of i the invention as claimed.

end portions disposed at one side of said bracket and provided with registering open ended slots parallel to the lay, a fastening element positioned in said aperture and extending through said slots whereby said plates are individually adjustably secured to said bracket, and a check strap having opposite ends thereof secured to intermediate portions of the respective plates and loosely embracing said picker stick, said plates extending in opposite directions from said bracket and having inwardly arcuated substantially J -shaped outer end portions terminating in substantially.v

opposed extremities and afiording substantially semi-circular abutments for the respective end portions of said strap when the picker stick 15 swings from one side to the other.
